Each of the given statements are true and together they explain how the removal of one species of large tree can cause an ecosystem collapse. Without the large palm trees, the soil is more vulnerable to erosion, which reduces productivity. Plants used to living in the shade of the trees lose their protection from direct sunlight. Additionally, the large trees serve as habitats for many other species, which can be lost when the trees are removed. Together, these factors can lead to ecological collapse.
